New York City, in partnership with the New York State Research and Development Authority (NYSERDA), most recently expanded the Carbon Challenge to include multifamily buildings. The City is partnering with leading property management firms that have committed to reduce greenhouse gas emissions from a portfolio of their multifamily residential buildings by 30% in ten years. The residential sector accounts for 37%of New York City's total emissions, making up the largest single source of emissions in the city. To date, 17 of the largest residential property management firms in the city have accepted to the Carbon Challenge, and are now in the process of signing up the individual multifamily buildings that they manage.

If you are a resident of a co-op, condo, or rental building that is interested in participating in the Carbon Challenge, please contact your property manager directly or email CarbonChallenge@cityhall.nyc.gov for more information.
